Title: Date display device
Inventor: KATSURAI HIROYUKI
IPC: H04N5/445
Filed: 1993-03-12
Abstract: PURPOSE:To make a picture easy to see by providing an object position discriminating circuit and a date position setting circuit to automatically change the display position of the date so that the date does not overlap the object. CONSTITUTION:The video signal picked up by a video camera 1 is inputted to an object position discriminating circuit 2. The, circuit 2 discriminates between the object and a background and sends the information to a date position setting circuit 3. The circuit 3 automatically sets such position of the date based on information from the object position discriminating circuit 2 that the date does not overlap on the object, and the information is set to a date generating circuit 4. The circuit 4 sends a date signal at this position to a date adding circuit 5, and the date signal is added to the video signal to display the date at the position other than the object. As the result, satisfactory photographing is performed without overlap of the date on the object during photographing of the video camera.

IPC: B63G8/08
Filed: 1988-03-07
Abstract: PURPOSE:To suppress reaction torque from a propeller by forcing a pair of propellers having mutually reversed pitches and coaxially arranged in double layers in the axial direction to turn reversely to each other by means of a counter rotating shaft to produce thrust. CONSTITUTION:A pair of driving means 14, 15 are supplied with electric power and driven in rotation in mutually opposite directions. Thereby, the inner/outer side rotary shaft 12, 13 of a counter rotating shaft 11 are rotated in mutually reverse directions so that a pair of propellers 25, 26 are driven in mutually reverse turns. The pair of propellers 25, 26 are constructed with mutually opposite pitches so that each thrust is generated in the same direction through mutually reversed driving. Further, reaction torque can be suppressed by rotations in both directions so that rotational force around the shell may be reduced.

Title: Equipment for taking out contents of box
Inventor: YONEDA AKEMASA
IPC: B66C1/62
Filed: 1988-03-04
Abstract: PURPOSE:To ease an impact due to falling and prevent solid bodies from chipping or cracking, by opening a controlling cover gradually while inhibiting the falling of the contents when a box is turned by a chuck and the opening is faced down. CONSTITUTION:A box 1, in which solid bodies 2 and powdery and granular material 3 are contained, is conveyed to the upper side of a conveyor 26. At this time, a geared motor 20 is started, and the box 1 is turned in the direction shown by the arrow A by a chuck 30b. When the box starts turning, the natural falling force of the solid body 2 and the powdery and granular material 3, which come out of the box 1 gradually, resists the spring force of a spring part 33, and a cover 32 is pressed and opened in the direction shown by the arrow B. Thus, the solid bodies 2 and the powdery and granular material 3 fall gradually without all falling together, the shock due to the falling is relieved, and the chipping or cracking can be prevented.

Filed: 1984-03-21
Abstract: PURPOSE:To improve absorbing efficiency of a laser beam by providing a reflecting means which reflects the laser beam reflected from the surface of a work and irradiates the same again to the surface of the work to the tip of a nozzle. CONSTITUTION:A laser beam 2 emitted from a laser oscillator is condensed by a condenser lens so as to focus near the surface 5 of a work. Part of the laser beam 2 irradiated to the surface 5 is absorbed into the work and heats the work but the greater part of the remaining laser beam reflects on the surface 5. The laser beam 7 reflected by the surface 5 is irradiated to a reflecting mirror 6 provided to a nozzle 4 and is again reflected by said mirror so as to be irradiated as a laser beam 8 to the work 5. The irradiating rate of the beam to the surface 5 is thus increased and the absorption efficiency is improved.

Title: Etching termination detecting method
Inventor: KOSHIMIZU CHISHIO
IPC: H01L21/302
Filed: 1994-02-25
Abstract: PURPOSE:To provide a method to accurately defect the etching termination point even when a silicon oxide film is etched under a comparatively lower pressure. CONSTITUTION:When the CF-based gas is introduced for the etching process, C2 which is an intermediate product produced by dissociation under the plasma shows a tendency to be adhered to an oxide film so long as silicon oxide film exits on a semiconductor wafer and light emitting intensity of C2 is comparatively lower during the progress of the etching process. When the process comes close to the etching termination point, amount of C2 adhered to the oxide film on the semiconductor substrate is reduced, when light emitting intensity of C2 is intensified. Meanwhile, since Si or SiFX (x=1 to 3) which is a reaction product with silicon oxide film shows a lower light emitting intensity because it is detected as a comparatively higher light emitting intensity during progress of the etching process and the oxide film is reduced when the etching comes close to the termination point. Therefore, the plasma termination point can be detected with higher accuracy by detecting a ratio or a difference between the light emitting intensity of C2 and that of Si or SiFX.

Abstract: PURPOSE:To manage data on measured values accurately and rapidly by attaching an identification code onto a monitor wafer, preparing a measured- value hysteresis file by using a correspondence file making the identification code and the identification symbol of a lot correspond to each other, and managing the data. CONSTITUTION:An identification code 20a is affixed previously onto a monitor wafer 20, and a correspondence file 24 making the identification code 20a and the identification symbol of a lot correspond to each other is recorded beforehand to a data processor. The monitor wafer 20 is measured and a measured value corresponding to the identification code 20a on the monitor wafer 20 is input to the data processor 23, and a measured-value hysteresis file 29 is prepared, referring to the correspondence file 24 by the data processor 23. Consequently, the identification code 20a attached onto the monitor wafer 20 is not separated from the monitor wafer 20, distinguishes the monitor wafer 20 from other monitor wafers, and functions as the clarification of correspondence relationship with the lot 21. Accordingly, even when a large number of the monitor wafers are measured collectively, correspondence relationship with the lot is not obscured, thus simply managing the data of the measured value accurately.
